Question

solve step by step explanation ​

Answer 1

Answer:

Hello mate

Here is your answer

Let the radius of the circle be r

Then, circumference of the circle = 2πr

And, Area = πr^2

Here ratio = πr^2/2πr= 9/4

=> r/2= 9/4

=> r = 9/2

=> r = 4.5

Now , circumference = 2πr= 2* π*4.5

= 9π cm

So, circumference of the circle = 9π cm
